Analog Devices Inc./Maxim Integrated MAX313CUE+

Overview

MAX313CUE+ from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) CMOS analog switch optimized for precision signal routing in bipolar and single-supply systems. It delivers 6.5Ω typical on-resistance, 1.5Ω max on-resistance matching between channels, and rail-to-rail signal handling across ±4.5V to ±20V dual supplies or +4.5V to +30V single supply - enabling low-distortion audio switching and high-fidelity data acquisition.

For engineers reviewing the MAX313CUE+ datasheet, MAX313CUE+ pinout, MAX313CUE+ application, or MAX313CUE+ equivalent, key selection criteria include guaranteed R_ON flatness (≤2Ω), <2.5nA off-leakage at +85°C, >96dB crosstalk at 20kHz, ESD tolerance >2000V per Method 3015.7, and TSSOP-16 packaging for space-constrained PCB layouts.

Technical Context

The MAX313CUE+ implements a fully complementary CMOS transmission-gate architecture with matched P- and N-channel devices per channel, ensuring symmetrical conduction and minimal charge injection (±30pC). Its logic interface accepts TTL/CMOS-compatible inputs referenced to VL (2.4V high, 0.8V low) independent of analog supply rails.

It supports true rail-to-rail analog signal switching from V− to V+, with guaranteed performance over the full specified analog range (e.g., ±10V with ±15V supplies). Break-before-make timing is not inherent - the MAX313 is strictly SPST NO - unlike the MAX314, which integrates mixed NO/NC topology.

Key Specifications

Pinout & Package

MAX313CUE+ is housed in a 16-pin TSSOP package (4.4mm width, 0.65mm pitch), RoHS-compliant and moisture-sensitive level 1 (MSL1).

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog switch applications.

Compared with MAX313EUE+, the MAX313CUE+ offers identical electrical performance but reduced thermal operating margin; compared with ADG411BRZ, it provides superior signal range, lower R_ON, and dual-supply flexibility - making it preferable for high-fidelity, wide-dynamic-range analog routing.

Availability

MAX313CUE+ is available at Aetrix Electronics and suitable for audio signal routing, test equipment multiplexing, and avionics signal conditioning requiring stable component supply, long-term lifecycle assurance, and RoHS-compliant TSSOP packaging.

Supply support for MAX313CUE+ includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a fabless semiconductor company specializing in high-performance analog, mixed-signal, and power-management ICs for industrial, communications, and consumer applications.

The MAX312/MAX313/MAX314 family was designed specifically for precision analog signal routing where low on-resistance, tight channel matching, and rail-to-rail operation are mandatory - targeting test & measurement, audio infrastructure, and high-reliability embedded systems.

FAQ

What is the maximum analog signal voltage range supported by the MAX313CUE+?

The MAX313CUE+ supports analog signals from V− to V+. With dual supplies of ±15V, it handles ±10V signals; with single supply (V− = GND, V+ = +12V), it routes 0V to +12V signals. Absolute maximum ratings allow V+ up to +44V and V− down to −44V, but functional analog range is constrained by supply rails and internal clamping diodes.

Is the MAX313CUE+ pin-compatible with the DG411 analog switch?

Yes, the MAX313CUE+ is explicitly pin-compatible with the DG411, DG412, and DG413. Its TSSOP-16 pinout matches the industry-standard layout for quad SPST switches, including identical IN/COM/NO terminal assignments and supply pin positions (V+, V−, GND, VL), enabling drop-in replacement in existing DG411-based designs.

Does the MAX313CUE+ require external pull-up or pull-down resistors on its logic inputs?

No, the MAX313CUE+ logic inputs (IN1–IN4) have built-in input hysteresis and accept standard TTL/CMOS logic levels (0.8V low, 2.4V high) referenced to VL. External biasing is unnecessary unless driving from open-drain or high-impedance sources - in which case a 10kΩ pull-up to VL is recommended for noise immunity.

Can the MAX313CUE+ operate from a single 5V supply?

Yes, the MAX313CUE+ operates from a single +4.5V to +30V supply. With V+ = +5V and V− tied to GND, it supports analog signals from 0V to +5V. However, R_ON increases (up to 25Ω typical) and dynamic performance (t_ON/t_OFF) degrades versus higher supply voltages - verify against load requirements in the Electrical Characteristics table.

What is the thermal performance difference between MAX313CUE+ and MAX313EUE+?

The MAX313CUE+ is characterized for 0°C to +70°C operation, while the MAX313EUE+ extends to −40°C to +85°C. Both share identical electrical specs at +25°C, but the E-grade version undergoes additional screening and testing across the full industrial temperature range - ensuring guaranteed R_ON, leakage, and timing performance under extreme ambient conditions.
